I am using the method encryptDecrypt at line number 235 to decrypt the challenge string sent by ONDC.
It gives pad block corrupted error, so I changed the line 249 to
Cipher cipher = Cipher.getInstance("AES/ECB/NoPadding", BouncyCastleProvider.PROVIDER_NAME);

It removes the padding error.
Decrypted challenge string by given code is not matching with expected decrypted string.
